I am in need of a few sizes of flat-bottomed holes.

The difference between HCS and HSS is well established, and worth the
extra few bucks to go to HSS.
But what about carbide?
Any sets you guys like? ( 1/4 - 1" in 1/8 increments would be fine.)
Lee Valley has a nice set.
Any other suggestions?

I have a set of Freud carbide forstner bits.

I wouldn't leave home without them.

SFWIW, the set comes with a 1-3/8 for 35mm hinges, but no 7/8 which I
added.

Use HHS brad points below 1/2" except for the 1/4 & 3/8 which are Freud.

If you want very good brad point drills, find a supplier to the die
cutting industry such as gasket houses.

My landlord is a gasket maker & has some very neat brad point drills.
